View attachment 275336 here is a photo of the arduino charge coil for the blue tooth.
I think that was a previous version. The one that's on Shapeways now is the third design, if I'm not mistaken. I'm going to be ordering mine soon, as well, and I'm going to try my hand at applying metal foil for the brushed aluminum parts. I'll post pics once that's done. I'm going to just do this one as a static piece, but I know that TSFG is still working on a fully functional one that's spring loaded with Bluetooth...
It's funny, before I found this thread and the detailed close up pics of the phone, I had thought that it opened by squeezing on the two black side pieces, not a small button on the side (actually, IIRC, that was the design originally discussed several pages back). If there was wiggle room it terms of accuracy, would that make it easier?
